This thread is devoted to my HO layout that I am building in my shed so I can still do something with trains when it is a. to hot to work on the G guage layout or b. it is to dark ie night time and I cannot work on the G guage. Some pictures of what I have done so far, the baseboards warped in the heat it was 35C when these were taken, in the cool morning they were flat again. I do have a problem with the corner shown in pics 24 & 27 the board is 4 foot square and will have a 500mm radius part circle as part of the return loop similar to pic 29. I will have to figure out a way to get access to the corner and the far edge of the base board a duck under/access hatch is not an option as underneath the layout there will be storage tracks for the G guage trains. The other end is not a problem as I have access to 3 sides.
